Question

7,1+5+(−8,4s)=7+7,1−8,9s.

Answer 1

7,1 + 5 + (-8,4s) = 7 + 7,1 - 8,9s

8,9s - 8,4s = 7 + 7,1 - 7,1 - 5

0,5s = 2

s = 2 : 0,5

s = 4

Answer 2

To solve for the variable "s" in the equation, let's perform the necessary operations to isolate "s" on one side of the equation:

Given equation: 7.1 + 5 + (-8.4s) = 7 + 7.1 - 8.9s

First, combine the constants on both sides of the equation:

12.1 - 8.4s = 14.1 - 8.9s

Now, let's isolate the "s" terms on one side of the equation by adding 8.9s to both sides:

12.1 - 8.4s + 8.9s = 14.1 - 8.9s + 8.9s

Simplify:

0.5s = 14.1

Finally, solve for "s" by dividing both sides of the equation by 0.5:

s = 14.1 / 0.5 s = 28.2

So, the solution for the equation is s = 28.2.
